Ships passing through the Panama Canal

Appearing in this Envisat radar image like shining jewels, ships pass from the man-made Lake Gatun through the Panama Canal across Central America.
The colour in this image is due to it being a multitemporal composite, made up of three Advanced Synthetic Aperture Radar (ASAR) images acquired on different dates, with separate colours assigned to each acquisition to highlight differences between them: Red for 16 March, Green for 12 Jan and blue for 14 October 2004. The view was acquired in ASAR Image Mode Precision, with pixel sampling of 12.5 metres.
